' WHEEL.

Illinois, have invented certain new `and use-4 ful Improvements in Wheels, of `which the following is ay specification.

My invention is an improvement in wheels, vand has for its object tofprovide in wheels for railway cars a construction wherein roller bearings are arranged `between the Wheels and the axle, or between the axle and the journal box,y and wherein the Wheels are rigidly connected.

In the drawings: y

n the embodiment of theinvention' shown f in Figs. 1 to 5 inclusive, the wheel and axle assembly consists of the axle 1 of usual construction, upon which are arranged the` ispressed upon the axle in the usualfman-V "screws 20."y This' housing diskor plate has' van opening forthe axle," and thevr screws 20 'engage' threaded f openings in the porkIn theembodiment shown in! Fig. lthe roller bearing is arranged within 'the'kwheels- In Fig. 6, however'the' bearing is outside the wheel, being arranged at one -face of' the' sleevebeing integral at its ends withthe webs, and the axle 1 is arranged within the sleeve. A suitable tire 6 is held on the rim 4portionv 3. of the wheehthe said tlre 6 .bemg

frusto-'conical peripherally as i shown, and

having 'the liange` for engaging theyinner edge of the rail.

vThe hub portion 2 of the Wheel hasa cenf ytr'al annular ribf71on its periphery, and this rib is adapted to be received within annular grooves 8 in the rollers 9 which form ythe rollery bearing. Each of these rollers as the bore'lO of each roller is reamed or counter-bored at itsv ends as shownk at A11, "to

receive bronze bushings' 12, which'have rar dial perforations as shown. Any preferred number of rollers may be arranged about 'the hub portion 2, and the rollers are yconnected by holding rings 13 attheir ends, the said of each ring 13.

A housing is provided for-the roller, bearing, the said housing consisting of three sections, namely a central section 15 and two similar lateral sections 16. The centralp'section l5 is composed oft'wo portions, each portion being a half circle,j and thesaid section is of greater thickness than thesections v16, and of a 'width such that it ywill fit` within thegrooves'S of they rollers.' Thev sections rloare continuous rings, and in placingv the housing, the portions of,y the ysection 15 yare `inner section of the ring 16 iits against the' web 4,4 as does alsothe inner edgeof the ring 18, and the outer section 16 is held in place by a housing disk19which yis secured to the outer edge" of the rim lportion 3 by wheel,in `che present instance the outer face.

. In thisconstruction the'whe'el 21 is-secured tothe axle 22, andv beyond the wheellon the the rib 25 engages. lThe assemblage 'ot rollers is held by the holding rings 28, in the same manner as the rollers 9 are held, and the housing for the rollers consists Vof the central section 29 and lateral sections 30 ysimilar to the sections l5 and 16 ot Fig. l.

. .A lring` 31 is arranged outside ofthese sections 29 and 30, and a rim portion 32 which corresponds to the rim portion 3 vof Fig. l, engages-outside of ythe ringl. This rim ,ortion, which corresponds 'to `the journal ox of the usual truck assembly and Which is adapted for connection With; the truck frame, has a .radial Web 34 which fits between,.at its inner edge, the lhub portion 24 Vof `the roller bearing yassembly andthe .hub

n of the Wheel 21. Ahousing plate 35 is secured to the outer face of the roller assembly to prevent displacement ot the outer section 30 kof the roller bearing housing.

,In Figs. 7 and 8 `is shown a modiied construction of housing for the roller assembly. In this arrangement, instead of making a central section 29 .and lateral sections V30,V

the housing is an integral structure in cross section, consisting of tivo semi-circular similar sections. Each of these sections has an internal central Arib for `engaging the grooves 8 of the rollers, andL at their abutting ends one section has a lug, and the other a Vrecess for receiving the flug. LThe sections .have registering openings Jfor receiving a key 37, and the bottom of the recess and the ends oithe sections and on each side'of the lugare inclined as indicated in Fig. 7 so that the ends abut Y.on lines inclined to radii of the ring.. The

outer ring S which corresponds to the elements 2 .of Fig. 1 is similarly arranged, consisting of sections `which abut at their ends on planes converging toward the center of the bearings. .As shownk in-Fig. 8 one section has lugs 39 and the other recesses 40 for receiving the lug, and the keys 41 are passed through registering openings in the sections.

VIn Figs. 9 andlO `the elements 49. and 43 corresponding to the v'elements 2 and l5-l6 of Fig. lare continuous solid integral'rings, each ring having a .central rib 44 and 45 `respectively for engaging the grooves of the rollers. Each ring 'is provided also atone point with a key Way 46 through Which'the rollers :may be inserted, and after the last `roller haslbeenplaced these openings'46 are I lledbyfkeysffi?. These keysv aresheld-from displacement `by elements corresponding to Ythe axle andfto the ring 18 of Fig. il. Because of the sectional constructionof Shown in Fig.- 7.,' it can be :placed on the inner side of the Wheel as can beH compensated for by regrinding. Y rlhe beveled ends meet on planes converging toward the centerofthe sections. and it Will be evident that grinding of these abutting ends Will make the diameter of the sections smaller. s

ln the construction shown in Fig. l, the ends of 'the axle are engaged with the usual journal boxes of the`truck assembly and should a roller break, or the lbearing be otherwise damaged, there can be no trouble from this cause, since -the axle can still rotate freely in the journal boxes.

Hence a broken bearing Will merely lock the Wheel to the axle.
